These sources provide a detailed comparative analysis of two significant ransomware threats: Crypto24 and LockBit. The first source offers a side-by-side comparison, establishing that LockBit operates as a massive Ransomware-as-a-Service (RaaS) model with highly variable tactics due to its use of affiliates, while the newer Crypto24 is characterized as a more centralized, stealth-focused group emerging in late 2023. Both employ double extortion and use living-off-the-land (LotL) techniques alongside custom tools for evasion, but Crypto24 emphasizes targeted EDR disabling, whereas LockBit utilizes a broader range of tools and platforms due to its scale. The second source, a threat analysis from Trend Micro, focuses exclusively on Crypto24's sophisticated, multi-stage attack chain, detailing how the group targets high-profile enterprises, maintains persistence through keyloggers and legitimate tools like PsExec, and utilizes a custom tool called RealBlindingEDR to bypass security controls during off-peak hours.

The sources consist of an in-depth LinkedIn article detailing the Crypto24 ransomware attack on a bank and a LinkedIn error page that suggests alternative content to explore. The article, written by Michael Slowik, explains how the Crypto24 group successfully breached the bank by exploiting basic security vulnerabilities such as weak passwords and poor network segmentation, mapping the attack steps to the MITRE ATT&CK framework. This extensive case study emphasizes that simplicity defeated sophistication as the attackers used readily available tools and exploited fundamental security failures, contrasting the incident with the CISA control framework to highlight where the bank failed to protect 700GB of sensitive data. The second source is a generic "page not found" message from LinkedIn that redirects users to various popular content topics and categories, including business, technology, and career advice.
